SPCIFICATIO forming part of Letters Patent No. 617,068, dated January 3, 1899. Applicationled March 6, 1896. Renewed December 31, 1897. SGIMNO. 665,257. (N model.)

To all whom it may concern:

Be it known that I, GEORGE P. YoUMANs, acitizen of the United States, residing at Galesburg, in the county of Kalamazoo, State of Michigan, have invented a new and useful Windmill, of which the following is a specification.

This invention has for its object to make the vertical support of the wheel-shaft and vane out of channel or angle iron or metal, with the bearing-block of the pitman having internal and external bearings against said support and adapted to slide up and down thereon, with a design to facilitate the construction and use with an increase in strength.

In the drawings forming a part of this speciiication, Figure 1 is an elevation of the mill with portion of vane and Wheel removed; Fig. 2, a cross-section on line o, cin Fig. 1, looking from a point above and enlarged; and Figs. 3 and A1 are the same, showing changes below described. Fig. 5 shows cross-sections more clearly illustrating the construction of the block and the support upon which it slides.

Referring to the parts of the drawings pointed out by numbers, 5 is the vertical revoluble support to the wheel-shaft 6 and vane 7. As shown in Figs. 1 and 2, this support is made Yfrom channel metal having one open side 8. The casting 9, which supports the wheel-shaft 6 and gears 10, is attached to the support 5 just above the derrick 11 and turns with the support 5 in the rotatable bearings of the latter at 12 in the top of the derrick 11 and at 13 in the cross-pieces lhwhich are attached to the derrick a little way down from the top.

The pitman which connects the wheehshaft 6 with the pump-rod 15 is shown at 16. This pitman connects with the wrist-pin 17 of one of the gears and with the pin 18 of a sliding block 19. This block 19 is formed so as to have an interior space or channel corresponding to the shape of the channel support 5 and in which space said channel is loosely placed. This construction provides the block 19 with an interior portion 20, which fits the interior of the channel support 5, Figs. 1 and 2. The pump-rod is attached at the upper end to the interior portion 2O of the block 19.

vBy this means when the mill is running the block 19 will play up and down on the support 5 with interior and exterior bearings against it.

By making the support 5 with one open side, as shown, access into it is easily eected in putting the parts together and in examining them and the pump-rod is housed and yet open to View and the support 5 is strong .and cheap to 4fit up and put into the mill. So, also, the chain or rod 21, with which the vane is pulled around when throwing the Wheel out of the Wind, Fig. 1, is exposed to easy examination in the open channel of the metal support 5. The upper part of this feature 221 is usually a chain, as in dotted lines in Fig. 1, and the lower part a rod, as shown; but this is of ordinary construction, except its location on an open channel.

Of course the gears 10 may be dispensed with, and the outer end of the wheel-shaft 6 may terminate in a crank, with which the pitman can connect, if desired, so far as this invention is concerned.

Fig. 3 shows the support 5 made from L.- shaped metal, and in Fig. 4 it is V form, and in both of these constructions the block 19 fits the exterior and interior, the same being shaped to correspond to the shape of the support 5. So it is seen that angle or channel metal of any suitable shape may be used and accomplish the same results.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-= A rotatable upright support made from angle or channel metal, combined with a bearing-block having the exterior and interior portions fitting the contour of the upright support both inside and outside and adapted to slide thereon, the block thus having an. interior tongue portion, and the pump-rod attached to said interior tongue portion, substantially as set forth.

In testimony of the foregoing I have hereunto set my hand in the presence of two witn nesses.

GEORGE I. YOUMANS.
